Neither of both ^{i.e.  trezor and ledger} can be viewed as alternative to Yubikey ^{5th series} which support FIDO2, U2f, PIV, OATH ^{TOTP and HOTP}, OTP ^{including HMAC-SHA1 Challenge-Response and Static Password}   and OpenPGP standards. I assume that "nobody complained about it" because nobody uses obsolete FIDO.

Once again, I prefer to have the separate specialized  gears  ^{like wallet, security key , encrypted storage IronKey and  etc. that have advanced features}. rather then a single crypto-combine were some parts  may be short-tailed. This give me more flexibility  in security and heritage  schemes as applied to my stash. ^{For instance, using this technique  I have openly spread  my SEED phrases over the whole word keeping them at my relatives and friends. How could I do it with the use of crypto combine other that to spend the fortune to buy dozens of its instances?}
