I think the proposal is interesting in that it could be an interesting way
to solve the dust problem. While most solutions to dust focus on reducing
how much are created and encouraging consolidating utxos to avoid them
becoming dust, this proposal could utilize dust for valuable purposes. Why
use valuable Bitcoin for NFTs or colored coins when dust can be split into
it's unit satoshis and used with no loss of utility?

Simple and elegant. I like it. If we're giving ACKs: ACK. Tho TBH I don't
see any reason NACK this - seems like this doesn't affect consensus,
doesn't affect relay, doesn't affect anything except people that run this
algorithm on the blockchain. If people want to do something like this,
people are going to do it whether or not the bitcoin community wants them
to. A standard would be good rather than everyone doing their own thing.

One thought I had was: what happens if/when it comes to pass that we
increase payment precision by going sub-satoshi on chain? It seems like it
would be fairly simple to extend that to ordinals by having fraction
ordinals like 1.1 or 4.85. Could be an interesting thought to add to the
proposal.

transaction outputs displace the older UTXO set entries, destroying the
ordinals contained in any unspent outputs of the first transaction.

What you mean by "the same transaction id" here is unclear. I was
interpreting the proposal to mean that UTXOs are all assigned a set of
ordinals, and when that UTXO is spent, it transfers it's ordinals to
outputs in the transaction the UTXO is spent in. Is that what you mean by
this sentence? If so, I'd suggest rewording.

This isn't true at all. Some bitcoins are indeed known to be stolen and
even blacklisted by some companies/governments. I don't see how ordinals
changes anything related to this.

@vjudeu

Those could be used for NFTs but not something like colored coins. It would
be a strict subset of ability, tho its an interesting idea in its own
right.
