If you are scraping off bits, why not instead _add_ one, but reserve
_all_ the additional tag values gained in that way for representing
integers?

Something like "tag byte values of 0 to 127 all represent integers,
tag byte values from 128 to 256 represent all other data types".

That way integers would go up to 1GB without pain.
