Motivation

The stack size limit of 1000 confuses even those who designed it.

It would be useful to have a test to demonstrate that a 999 of 999 Taproot multisig is possible: multi_a(999, P1, …, P999). Especially to make sure our wallet can spend from it and doesn't allow a bigger one (no 999 of 1000 and no 1 of 1000).

Possible solution

Either expand the descriptors unit test and/or one of the wallet functional tests.

Useful Skills

Python and a basic understanding of output descriptors. Understanding (Mini)script (interpreter) is not necessary unless you actually want to understand why the limit is there.
