I'm not 100% certain, but, yes, I think it's a combination of that, and
the fact that nobody's actually gone and tried to make that change to
RDMD yet.

AIUI, The original motivating purpose for RDMD was to be able to execute
a D source file as if it were a script. So finding all relevant source
files, passing them to DMD, etc, was all just necessary steps towards
that end. Which turned out to also be useful in many cases for general
project building.
