In my opinion, the point is:

1) Different (compiled) versions of the RTL are required for real Linux
and Android anyway, so it makes sense to declare them as two distinct
targets (similarly to e.g. Darwin and FreeBSD).

2) As you correctly mention, the difference in behaviour requires someone
to take care about possible incompatibilities actively. The behaviour of
the platform differs and you cannot expect that current maintainers of the
Linux port take responsibility for testing Android compatibility in
addition to the Linux compatibility. Obviously, people making changes
should be aware that some parts are shared (similarly to Jonas and Marco
discussing impacts of some BSD related changes), but that doesn't mean
that everything always works out of the box.
