Um... what are "reasons"? If Geary calls 
webkit_web_context_set_web_extensions_directory() with the correct 
directory then web extensions under /usr/local should work just fine.

No, Epiphany installs its web extension into libdir/epiphany. That's 
/usr/lib64/epiphany on Fedora. Where did you find it under libexec? Of 
course it doesn't belong there.
