I wear a respirator instead and Face ID works fine through it, so that hasn't been a problem for me. I certainly understand it's been a common complaint however, and I'd fully support Apple adding in-screen Touch ID. I just don't think that'd be a good replacement for Face ID, which all security discussions aside simply serves use cases (like wearing gloves) that Touch ID doesn't even as Touch ID serves cases that Face ID doesn't. It'd be better to have both. Kind of too bad Apple couldn't have at least attempted to help more people out purely in software though. I use a complex password along with Face ID as well, but there isn't any inherent reason they couldn't have more of a step function there: complex master password for performing sensitive functions, then a PIN fallback for Face ID, then Face ID like normal. Complex master required for trusting devices, upgrades, installing profiles, etc, PIN/biometric for typical out-and-about functionality.
