It is. Android multi-ABI is "building Qt for Android for multiple ABIs
in one go" instead of "building Qt per ABI". The former was added to Qt
5.14.0 and is not crucial to provide Android support.

The idea is to have one source of truth instead of two.
Right now we (CMake guys) consider the pro files to be the source. But
people tend to make manual adjustments to the CMake files which creates
extra work for re-generating them.
Another advantage of removing the pro files is: reduced CI build times.
When would be a convenient time for you to remove the qmake project
files? We certainly don't want to keep them around forever.
