Ok, I have finished implementing all functionality required to do a full transfer, from coin selection (including co-operative bitcoin and RGB coin selection), PSBT creation, DBC commitments (with possible combination of oprets/taprets, which are automatically deduced from the inputs) to the consignment creation - all in just a single method call (and in single cli command transfer):

    let (psbt, meta, transfer) = rgb.pay(invoice, method, params)

I have no idea whether it works (pretty sure there are some bugs) - I will be debugging during the next few days. But at least, with the code written and compiling now I am sure we have everything we need in all our libraries (there are around 20 of them involved here) to have real RGB taproot wallets - a journey which took 3 years of my time and required implementing even taproot itself, twice (once in rust-bitcoin, second time in bp-std)...

Should there be a default value for this?

it is a flag, thus "default value" is false assigned when the flag is absent
