I think if we all really think we are better off in the long run not
having defaults, we probably want to do this over 2 releases and give an
advance warning that the change is coming. In JDK 12, we could emit a
warning, ex:
$ keytool -genkeypair ...
Warning: the default keypair alg (DSA) is a legacy algorithm and is no
longer recommended. In the next release of the JDK, defaults will be
removed and the -keyalg option must be specified.
(that's a bit wordy, but you get the idea)

If not DSA, should RSA be the new default? Or maybe RSASSA-PSS (I

We don't have an option to specify ECCurve in keytool yet (a string
-keysize).

I would rather get rid of the default completely.

In addition to the usual problems with defaults, there is also the issue
that the user doesn't specify how the key pair can be used. The current
default produces a key that can only be used with signatures, but if we
change the default, then the key may also be used for encryption (RSA)
or key agreement (EC). I worry about the problems that can arise if we
change the default in a way that increases the capability of the key
pair that is produced.
