Granted, knowledge about the applicable grace periods reveals potential
refunds upon deletion, but not the actual amounts.

That said, I agree that conducting time-based checks based on a concrete
domain's life cycle status for a <fee:check> seems excessive, especially
since the actual outcome of a deletion may be different even if it is
performed only seconds later.

While our current implementation of <fee:check> (for fee-0.11) returns
expected fees based on the launch phase a specified domain was
registered in (if the domain exists), it does not consider any other
attributes of the domain in question. I believe it a good idea to retain
this behavior for checks on domain deletion, effectively meaning that
(in a standard pricing model where deletions are free and no refund is
granted outside of grace periods) no fees or credits would ever be
returned by a fee check for the "delete" command.

However (going back to Matthieu's question), I believe the fee extension
in a response to an actual <domain:delete> should indeed return the
actual credits granted if the domain is within some grace period(s) at
the time of deletion.

Best regards,

Thomas
