It took a long time to me to answer that.

From the Zen of python:

python -m this

"Special cases aren't special enough to break the rules.
Although practicality beats purity."

We do it because it is practical.

The change mentioned have been tested in the next stable series, in that case 
2.1.5 was only released after 2.2.0 was released.

Not only that but IIRC we never had any significant bug in the previous code.

In the particular case of lyx2lyx I compare the output that comes from 
converting different manual, like the User Guide.

The new release has probably has other fixes.

In summary I disagree strongly that "basically, cherry-picking a few fixes 
would be more effective". The maintenance of other projects disproves that
