...Except that you're loosing flexibility (serialization, deserialization)
which gives you BIP32 node.
I see "bip32 seed" as some transitional, internal state from raw entropy to
bip32 master node and this seed should not be handled by the end user in
any form. In the oposite, well-serialized bip32 node (in xpriv, or even in
mnemonic format) can be used very widely and have no downsides against
using raw "bip32 seed".

I also don't care too much about altcoins, but people want them so me, as
infrastructure developer, need to think about it. And I don't see any
reason for breaking compatibility between Bitcoin and other altcoins. I
would be happier if there will be another sentence than "Bitcoin seed", but
honestly, who cares. It is just some magic string for hashing the raw
seed...

The truth is that even existing software which handle bip32 don't care
about 'version' at all. I think that "xpub/xprv" distinction is the only
useful feature of version, so user se if it stores public or private
information.
But using prefixes which doesn't enforce anything is even more dangerous.
If somebody exports node "dogeblablabla", it creates false exceptations
that there's only dogecoin stored.
