I would view this as an optional server feature, so if a server does not
want to support a client-specified value they don¹t have to and should
return a 2102 to the client in a similar fashion to the maxSigLife.  If they
did support a client-specified value the floor and ceiling values is a
server policy decision.  It would be nice if the server did return the
server-side default TTL for the DNSSEC resource records to help define the
maximum wait period, but again that would be optional.  If the visibility
and setting of the ttl will assist in the transfers, than it would be good
if the protocol did provide support for it.  I guess I want to understand if
others see the benefit of this.

Possibly, if a reasonable tradeoff can be made here.  Of course, if we have
wording about server policy being able to define the floor and ceiling, then
technically operators could force it to be a single value, if they so
desired.
