It would still just be doing one thing - sleeping. Support for units
usually comes under  "and does it well". I wouldn't want to have to
pipe df through awk to get MBs, or complicate "find" with arithmetic.

Unit support in sleep is a perfectly legitimate thing to ask for, I
don't think it particularly useful though, and leap-second support is
close to pointless.
