Why is it nessesary to use discouraged theorems here? Aren't there corresponding not discouraged theorems available?

The short answer is that the two choices are to use https://us.metamath.org/ileuni/cnfldmul.html (already in iset.mm) or add mpocnfldmul (as it is stated in set.mm). The most plausible way to prove mpocnfldmul in the short run is via ax-mulf. The cnfldmul approach wouldn't show up as an additional use of a discouraged theorem but it would actually entrench ax-mulf further.

I don't know how familiar you are with the ax-mulf background but in a nutshell:

There are also some dissenting voices:

I'm not really trying to get involved in something which is still being worked out in set.mm - I am just trying to follow current set.mm practice as readily as can be done without a large amount of effort.

OK, if this is still in discussion in set.mm, we can take its current state over to iset.mm.

Yeah, that's pretty much the situation. Even if/when things settle down in set.mm, it is still work to bring it over to iset.mm (adjusting as needed for the differences between the two) - my philosophy for how to do that is "one step at a time".
