Just to clarify, we are talking about systemd-networkd here: No, it's 
the total opposite of stable. I had to experience two breaking changes 
lately, before I decided to migrate away from it.

First: The matching logic of its config files changed. From the start 
on, config files without a Match section matched everything. Now they 
match nothing, leaving some of my servers without connectivity after 
upgrade.

Second: You cannot use its DHCP feature without systemd-resolved 
anymore. The latter has the nasty bug of compiled-in fallback DNS 
servers, that you cannot disable via config files; leaking private data 
to Google or Cloudflare or allowing masquerade attacks, in case of local 
DNS problems. Even Fedora is patching that stuff out now AFAIK.
