It wouldn't break the Ada semantics, but it would make it a lot harder for 
build tools and the like to function. (Especially simple tools like 
"find"/"grep".) And in any case, the solution for "overlong file names" is 
to use shorter ones! There's no law (either in GNAT or Ada) requiring anyone 
to use 50 character file names.

Indeed, most of my Janus/Ada work still uses 8.3 file names: "J2Code_E.Ads", 
for example. The actual package name is quite a bit longer. Janus/Ada needs 
only to be told once about the correspondence between package names and file 
names -- either by compiling the file manually or telling the build tool the 
name when asked. After that, Janus/Ada remembers the file names in the 
project files and does not need to told again (unless of course you decide 
to make a fresh start with your projects and delete the old file).
