Disagree on general principle.

Putting seldom-used 'features' into defaults seems harmless a few bytes
at a time...

And this one-more-small-chunk may or may not affect resources needs.

But it means more code to maintain and debug 'forever' - not just document.

Note that we've just seen moves to pull perl and such *out* of the defaults.

And that 'real' DB's (PostgreSQL, mySQL, et al) need to be optioned IN,
not OUT.

KISS

Exim is not competing with the Linux kernel for bloat.
