OK, I forgot to sub -1 from 1, oops.  So it's not very even, but...

We have a lot of variation and no "standard" aside from "board
maintainer picks".  While I'd strongly question anyone who did > 10 I
think this is a board maintainer decision.  Now, if you've convinced
Fabio that 5 or 3 just makes more sense than 1 for all the right
reasons, great.  But "I think 1 is too short" isn't a good one.  1 is
plenty of time to get a keypress in and stop the boot given that you
have roughly from u-boot starting to press any key, not just when the
countdown is going.  Unless you have a bug in your timer code :)
