Is anyone maintaining a lightweight version of Bitcoin Core that only has legacy address support, segwit support, and coin control? I don't really need Taproot, or any other things that add complexity in the code. Im even ok with legacy only, since I rarely make transactions, and anything after legacy for me adds a tradeoff in security no way how you want to put it, so for me all these are just cluttering the thing for no reason. One thing I find useful is the generation of a PSBT file so you cannot screw up with the command line when generating a raw transaction and then sending it into the online node to broadcast. But I would like to be able to remove anything that cluters up the code with many things I will never use. I just need to be able to send and recieve from A to B. I feel like Bitcoin Core from 10 years ago with whatever really necessary bugs that were found fixed would do.
How do you intend to send from A to B if B is giving you a taproot address? Outside of my signature campaign payments here, and brutally honest when I am too lazy to generate a new address and reuse an old one I have handy, by default my wallet only generates taproot.
And keep in mind taproot allows the use of Schnorr Signatures, which offers better security.
But anyway, there is nothing that really does what you want. You could probably put together something and compile it yourself but that's about it.
