+  Why split from ./default.nix?
+
+  ngtcp2 libs contain helpers to plug into various crypto libs (gnutls, patched openssl, ...).
+  Building multiple of them while keeping closures separable would be relatively complicated.
+  Separating the builds is easier for now; the missed opportunity to share the 0.3--0.4 MB
+  library isn't such a big deal.
+
+  Moreover upstream still commonly does incompatible changes, so agreeing
+  on a single version might be hard sometimes.  That's why it seemed simpler
+  to completely separate the nix expressions, too.
