I don't want to get extra gifts for myself if that means someone's browsing the requests for treats and makes one for me instead of treating that person with 3 requests of the heart that they could write for with a little more time in canon review.

That's a big assumption. If I can't treat someone with the thing I want to write, I won't say "oh, I'll do canon review for something else and write something else", I'll just... don't write any treats.
