The "killer feature" for public-pool solo mining on a custom node like nostr:npub1aghreq2dpz3h3799hrawev5gf5zc2kt4ch9ykhp9utt0jd3gdu2qtlmhct would be the ability to prioritize my own transactions to the current block template.
Once I'm mining at home with bitaxe in my own pool, why not mine my own transactions? 😎

I think in certain situation it can create link between your transaction and your block reward adress if you mine it with lesser fee then rest transactions in block. It's not certain, but when you pay small fee and other don't, there is some probability that miner is also that UTXO owner.
That's true, but also the decision (not) to do it is up to the miner, so no problem detected there.
