The latest draft is at 1.29:

https://tianocore-docs.github.io/edk2-InfSpecification/draft/#edk-ii-module-information-inf-file-specification

(also visible at the bottom of the README.md changelog at your link
<https://github.com/tianocore-docs/edk2-InfSpecification>),

for addressing TianoCore#1952 (MODULE_TYPE=HOST_APPLICATION).

And, there is already a good number of modules present in both edk2 and
edk2-devel that specify "INF_VERSION = 1.29".

I figured we'd want to break away cleanly even from the draft (= latest
unreleased) spec.

Thanks!
Laszlo
