Semantic versioning is the reason that the 2.7.0 official release has
been postponed for a long time, since we added source-compatible, but
binary incompatible changes (adding virtual functions mostly, or
adding default arguments). Each such change would have required a
2.N+1 release, once it was branched from master. We solved it by
always building from source and sticking to master.

Apart from that, I agree that sem ver is the clearest and most
necessary thing to do such that users can rely on this when upgrading
their toolchain.
