For someone who knows their way around YACC/BISON, a grammar for any of 
these assemblers is probably a few hours of effort.  From there, it's 
off the C (I think you can generate a YACC grammar into C code) or just 
call your grammar from your favorite scripting language.

But yes, I am sure it's not trivial.  Just that it seems better to do 
that than to dumb down all the source to fit all the assemblers.

There's probably a "law" about this and other compatibility facets. 
Something to the effect of:

The amount of features one can use in a supposedly "standard" format is 
inversely proportional to the number of programs that need to consume 
said format...
