The current control file lists (among others) the following build dependencies:

python3-numpy <!nocheck>,
python3-opencv <!nocheck>,
python3-pil <!nocheck>,

None of them are actually build dependencies. numpy used to be one in
pre 2.x times. Some unit tests are disabled if those packages are not
available.

While at it: libopencv-dev is not a build dependency either.

Don't worry, they are all used only in post-build unit tests as well as 
post-build smoke tests.
The <!nocheck> marker means they are for tests only. In environments where
post-build tests are not necessary, they won't be installed as 
build-dependencies.
In other word, the current status quo is fine and need not any change. Of 
course, adding
an autopkgtest will make it better.

Best,
Boyuan Yang
