At the same time, this was the exact older wording
they updated in the FAQ in 2018, before they then revised it to the current AskMH FAQ answer in 2022, so I would still take it with a grain of salt…
Also, see
here an example where a FTer was even rejected in 2018 for a MH -> SQ interlining (starting at HKG), and this was on a KUL-SIN SQ flight which even had codesharing as an option…

Definitely doesn’t hurt to ask, and SEA-based agents are more likely to agree to such requests.
But as the request could easily also be declined, a traveler should ensure any entry requirements - for Singapore in this case - are met as well as ensuring sufficient time between flights to exit, grab & recheck bags and re-enter at the connecting airport… at SIN, that is usually fairly straightforward and can easily be done with 2-3 hours transit time, if the incoming flight is not delayed.
