Would this mean, that the volumes in existing projects would be mapped
with a 0.5 factor, so that a volume of 200% in an old project would be
set to 100%?

We'd still basically have the same scale, but the numbers would be
different? What about the accuracy of the scale, would that be preserved?

One thing that should be an important consideration in making the
decision: are the note volumes stored as floating point or integer
values currently? If it's integers, then a smaller scale would be bad,
because we'd lose accuracy, and 0-100 in integers isn't even as accurate
as the MIDI velocity scale (and maps unevenly to it).

One possibility would be to just change the scale to 0-127, so that we
could map it accurately to MIDI velocities. This might make sense
especially if we're planning on implementing support for more external
instrument types in the future, such as LinuxVST, which also use MIDI...
and MIDI is still, despite being kind of outdated, an industry standard.
