Regardless if an airline requests it. Just do it.
You as a pilot should have your licenses valid if you are actively flying or planning to anyways. It goes to show you either didn't fly, or cared enough about staying proficient.
It's an extremely expensive profession to get into and I am speaking from experience as someone who kept minimum ratings valid (MEIR etc) for 3 years while converting to EASA/looking for work.
Even had to do an MCC even though EASA said I was exempted to get my foot in the door. (airline said I needed it so I got it)
