You installed the special "make it even harder to use" version didn't
you?  Because for me (gpg 2.4.3) it gives

Which shows all the subkeys and their expiration dates.  I admit it
doesn't show the fingerprints and you have to know you've requested a
subkey and it's showing the master record.

OK, OK, I can do longer expiration dates.

I can't really fix the subkeys bit.  The reason I have a signing subkey
is because on my laptop it's TPM resident but with the authorization
password in gnome-keyring, so I unlock it on login (and so, for me, it
just works for all the day to day signing operations).  My master key
is also TPM resident but with a different password that doesn't unlock
on login to try to keep it more secure and because I only need to use
it when extending expiration dates or signing someone else's key.

Heh, well to paraphrase Churchill: gpg is the worst key management
system ... except for all the other key management systems out there
...
