Note to self: avoid purchasing a camera that does this!

I wonder if it makes sense at all to change the pixel aspect ratio? I
think that is a little more convenient than crop on each clip.

I am not sure that is best. What about footage that is not from the
EOS 550D - it will be cropped. And you have to make the custom project
profile, remember to use it, and remember this procedure (easy for you
and I but maybe not for someone editing a few times a year).

I can not tell you why right now, but I will take a look into. The way
crop is integrated is special. It is probably something simple.
However, I think we might want to think about another remedy. I am not
sure what right now. It would be interesting to see what people are
doing on other editors and platforms.
