As someone who has been a dilettante on this subject for ~25 years, I
believe that the right thing to do is as follows:

Ledgers contain accounts. Accounts can represent anything denominated in
the currency of the ledger. a "ledger supporting multicurrencies account"
must be interpreted as multiple ledgers administratively linking one
account in each to the same identity.

The alternative destroys fungibility within the "ledger" abstraction, and
would require breaking into per-currency "subledgers" anyway, so just don't.
