Solution

Optionally include pending transactions while building a block via suavex_buildEthBlock and suavex_buildEthBlockFromBundles.

I like it, small nit but maybe fillPending is a better name?

Sure! Just to clarify, usePending -> fillPending or commitPendingTxs -> fillPending?

the first, my thinking is roughly: usePending only means use pending transactions when actually what this is doing is filling the rest of the block with pending transactions

btw, do you mind adding this change to the specs as well, you might need to update precompile and the suave ex namespace section.

Made the renaming changes. Regarding the spec update, I didn't find anything mentioning the composition of BuildBlockArgs ... not really confident about where exactly to add the struct definition in precompiles and suavex call.
