Current version of TLS (>1.3) do not support RSA (and various other cipher suites) for security reasons.
That is true for the key exchange part because RSA does not offer forward security. For signatures RSA is still used and probably still the most widely spread type of x509 certs.
I know Safari just upped the requirements to 2048bit keys for RSA not too long ago (for signatures).
