Actually, the newest Bitcoin app that they released a few weeks ago is smaller. The size shrank from 62kb to 56kb if I remembered the numbers correctly. I was surprised to see it.
Maybe that is true for latest version, but I am hearing complains from other people that apps for other coins increased a lot in size, for example BCH shitcoin app increased around 15 to 20 times.
I don't if it is somehow possible to check size of all apps and change before update, without installing and testing them individually.
One good news for ledger users is that Fido 2 should be supported in ledger now, that can be useful for everyone:
