As you might have already read. Though Liberation 1.0 and Liberation 2.0
has same outline in source files the difference is the Hinting
instructions. Hinting instructions differ in both. Due to community
preferring old Liberation 1.0 hinting. Decision is made to go with
Liberation 1.0.

Yes, Regression was identified.
In fact i am also thinking on this line. We have couple of bugs pending
[4][5] in Fedora against Liberation 1.0 to add some more characters. At the
same time the same characters are already available in Liberation 2.0.

Problem is Liberation 1.0 and 2.0 License are incompatible (OFL and
Liberation) so we can't copy Liberation 2.0 huge glyph set to Liberation

Option is
1. Tweak/Modify Liberation 2.0 hinting instructions to match Liberation
1.0. That is big task
2. Adding more glyphs to Liberation 1.0, this is also big one.

Presently nothing is happening on this both option.

No. Liberation 1.0 is not deferred in favor of other font. Since there is
no alternative font providing same crisp hinting effect and same time have
more glyph coverage. Fedora still uses Liberation 1.0 and if there are any
major bugs upstream is ready to fix and make new releases.

What version of Liberation does Debian ships presently?
