This is the OpenSSL model which httpd effectively mirrors today, although
their .x is an alpha sequence, and your proposal could be read with either

However, OpenSSL changes very little in terms of it's scope, and isn't the
best model for an evolutionary, development driven project like httpd.

1.0.0 and 1.1.0 both refactored much of the API in terms of opacity of internal
data members.

1.0.0, 1.0.1, 1.0.2 were incremental TLS features, but as these were defined
by spec, the scope of those upgrades was clear.

So I'd anticipate 1.1.1 if the API is extended further for new TLS features
without other changes, or I'd anticipate 1.2.0 if the API will be further
refactored (or both.)

But given the amount of recoding required to migrate from 1.0.x -> 1.1.0,
as illustrated by a bunch of patches here for mod_ssl, most modern
developers would have considered that rework a 2.0 scope change.

At least the OpenSSL project accomplishes what you outlined above,
irrespective of their number-alpha'ing schema.
