Other option would be to add "make-custom" check, and leave it unconfigured.

Supporting multiple `make_x` would be best, as there may be more than one of these.

I don't, which is why I think this is not a blocker, but it would be better to have.  While there was no issue I could find for adding the customization, I can see that someone may configure the check, wanting to add a second `make_x`.

Either way, something like adding `misc-make-smart-ptr` should be done, in order to keep the functionality of the other two in place. I added the check to misc, but `readability` would fit as well. I wouldn't go for `modernize`, because in that context, it doesn't have to be a modernization.
