Agreed.
In contrast, BIP37 as used today is totally decentralized, and can me
made much more secure, private, and scalable -- without giving up the
utility of unconfirmed transactions.
Please don't read into this statement a belief that all the coffees
should go on the chain, or that the security or privacy of BIP37 compare
favorably to any other particular thing.

You might as well replace Bitcoin with a system where these parties
sign transactions and skip mining altogether, it would have the same
properties and be significantly more effient.

The best way is to connect to the mempool of each miner and check to
see if they have your txid in their mempool.

If each of these services return "True", and you know those services
so not engage in RBF, then you can assume with great confidence that
your transaction will be in the next block, or in a block very soon.
If any one of those services return "False", then you must assume that
it is possible that there is a double spend floating around, and that
you should wait to see if that tx gets confirmed. The problem is that
not every pool runs such a service to check the contents of their
mempool...
This is an example of mining centralization increasing the security of
zero confirm. If more people mined, this method will not work as well
because it would require you to call the API of hundreds of different
potential block creators.
