tlug: su vs. su -l

I recently read the man page (first time for everything) and discovered the
"-l" switch for su, which gives me the environment of that user. Very
useful (especially for the PATH).

What I can't work out is why this is not the default behaviour (with a flag
to explicitly say you don't want their environment). Is there some
disadvantage to "su -l" and "su -l someuser"? Some security issue?
