Is CAIP-10 too constrictive for Hedera and Hive?

[bumblefudge]

Both Hedera and Hive encode heirarchies and/or checksums into their native addressing schemes with . and/or - characters-- should CAIP-10 be upgraded at some point to expand their regex to include those two characters for more straight-forward support of Hedera, Hive, and perhaps other chains I know nothing about? (note to self: old regex should go into Backwards Compat section if so!)
