Sure, great, let me just rebuild all my docker images on every single machine they run on thereby completely defeating the point of having images in the first place.
You run docker-compose build ONCE and you're set. On my machine, it takes five seconds.
Heck, you can even run docker-compose build everytime you start the application, it will use the cached build and take less than one second.

Correction: the docker-compose up -d takes care of the build process the first time it runs.
Literally, it takes more to complain about the issue than build the image ONCE.
I don't think the reproducibility is out. It's the same app, the same image, the same intended user, you just inject, once, the local user and group ids.
