Dear Tom,

Is there any reason for not chosing the more standard 5 second delay?
Ok, so let's go with 3 seconds then ;-)
There's a pretty even distribution of 1 3 and 5 second delays (with a few 10s, 2s and 6s). If they want 1, let them have 1, it's not hard to break into, you have U-Boot starting + 1sec.
The question is who "they" are. My vote is for 5 :-)
A quick AWK oneliner in include/configs finds this statistics:
OK, I forgot to sub -1 from 1, oops. So it's not very even, but...
Value Count -1: 49 0: 12 1: 59 2: 30 3: 150 5: 175 6: 14 10: 38 20: 1
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 :)
