That’s assuming that the wireguard protocol is not blocked by that same DPI that you’re trying to circumvent. The more tools - the better

Not at all. The protocol has a very well defined structure, and one only has to foul the handshake packets to block connections.

No, it used to as a side-effect, but DPI circumvention is an unpopularity contest... wiregaurd is no longer unpopular enough, DPI targets it, and wiregaurd's purpose is not to play the circumvent DPI game, so it's not going to continually make arbitrary changes to do so.

Witeguard isn't made to do this . Even the author said so . It's blocked in many countries
