30 years from now 3/4 plywood will measure just enough larger than 5/8 so
you won't be able to make a single pass with a 5/8 router bit.

You're right of course, but it occurs to me that 30 years ago when one
went
to buy 3/4" plywood, it *was* 3/4" and your one 3/4" router bit would
usually suffice.
