Right; NM uses dhclient or dhcpcd as the actual DHCP client, and if
these support FORCERENEW, then it'll work.  NM does nothing to suppress
any FORCERENEW capability that these clients might provide.  If NM fails
to handle any state changes a result of FORCERENEW (if renew fails or a
new address is obtained and NM does not update the interface's address
for example) then that's a bug that we should fix.
