Typical, when 'FAA pilots' discuss CPL requirements/checkrides/LST with Euro/UK based pilots who may not be aware of the differences mutually. Also in Europe, the IR is more often part of CPL module 'period' since people need more solo time after PPL and all the nuances and not to overspend. Again, different to FAA system where people have more options to use the flight time efficiently with training working on the 61.129 requirements.
For FAA land, just do the stuff in twin. Saves you doing the 10hr min on complex SE and since you probably have done the IR checkride, all you do is asym ILS approach, I believe. Haven't done twin flying yet, but that's what I sussed out so far.
Aiming for airlines, the ASEL CPL, including complex ASEL time isn't of much use unless for other (GA flying) use.
As for UK, the multi flying is DAMN EXPENSIVE and the checkride fees for retest and the rental again, cost a lot, so there goes the argument against, as given by UK pilots. Just FYI, it doens't relate to original query.
