To be clear, long Base32H numbers are definitely in scope (which is why the specification "recommends" a binary encoding scheme for this exact purpose, and why things like public keys/signatures are mentioned among the proposed use cases). Yeah, it'd suck for a human to have to manually record or dictate large-ish (more than 1kb / 1600 digits) sets of data, but it sucks at least a little bit less when you already know that everything can be assumed to be uppercase.
