Porting is rarely about being possible or not, more a case of how much investment vs level of return + sacrifice on the OG experience/vision. The big investment required is why you had whole external development studios porting experiences like Doom to Switch 1 or Saber Interactive porting Witcher 3, versus Capcom managing RE9 to S2 internally, late in development and still having it arrive alongside their original release target with a comparable experience. 

The fact that none of the Switch 1 ports you listed were done internally tells you how much they would have derailed internal teams schedule and priorities. Again, I just wouldn't see it as low effort before versus tons of effort now. It's been a calculated effort across both generation which is why you had all the PS3/360 gen RE games and prior natively ported to Switch. For me it just comes back to this

"S2 actually fits in with their ecosystem instead of requiring them to shift their ecosystem specifically to incorporate Nintendo."

Porting is much easier now on Switch 2, true, but there wasn't anything stopping Capcom from say just enlisting a studio like Saber or Virtuos to do it for them as so many other publishers did on Switch 1.

If something like Doom or Wolfenstein did well enough on Switch to justify continued support, I'm sure Resident Evil could have been profitable.

It's all water under the bridge at this point of course.

There is x amount of these porting studios though, I don't think its always simple when taking into account specific timing, resource availability etc. Arguably there are teams who put more resources aside to get current gen ports over but technically what capcom done with Monster Hunter Rise is worth much more than most late ports and Capcom has overall more Switch 1 content than most third party developers/publishers. Even the effort to port the backlogue of RE games is something a lot of devs didn't bother with.

Of course having a port of RE7 would have been brilliant and the icing on the cake, but calling their support half-assed feels ignorant of the actual forces at play including technological and maintaining the experiences/expectation they actually created with their PS4/PC games. But as you said, water under the bridge.

Technically I said it was half-hearted, I wouldn't call it half-assed as that feels much harsher, to me at least.

The older RE ports on Switch 1 weren't great though, RE5 and 6 ran poorly, while RE4 inexplicably lacked gyro aiming. They did feel very barebones and not up to the level of some other publisher's ports.

Oh that is a sad omission, fair 

Yeah it was the weirdest thing cos RE5, 6, Revelations, and Revelations 2 all had it, but 4 didn't for some reason. Just bizarre.

Anyway, not to derail things too much, but it's nice that we're getting much, much better ports now and hopefully that trend continues with MH Wilds.

It will be a challenging game to convert to Switch 2 I expect, as it's way more demanding on PS5/Xbox Series than it should be, but hopefully they can nip and tuck carefully to bring it across in a decent state.
