Yes the main reason for that is that the Makefile is not aware of which
files are lexical and can be compiled and which are dynamic and can't.

I'm not sure I understand.  I you mean that manually byte-compiling a
file prevents the .eln compilation to happen if make is invoked
afterwards then yes.  But make should be used.

I don't think so, the .elc is renamed with their final filename after
the .eln has been produced to prevent exactly that.

This build system arrangement is till we have dynamic scope compilation
and we can clean it up.
