NO! That way leads to madness.
That was the function of the autorequire flag on older gemspecs. That
lead to early loading of code before the complete gem version
requirements were given. This could lead to incompatible version of
the library being required.
It was also the root cause of causing require "FILE" to return false
instead of true. A bug the pragmatically effected absolutely no one
(who checks the return value of require?), but caused no end of
questions because people would do a require in irb and see the false
and think the file wasn't loaded.
The autorequire flag was also the root cause of several other issues
which escape me at the moment.
BTW, the only difference between the old require_gem and gem methods
is that gem ignores the autorequire flag.
