Yes, it is.

It holds the regression results from the "last known good" release
(usually the last official release).

The above is basically all there is to it. WRT 1.34, you might find
this message to be of a help:

In a number of limited cases, yes.

If you can guarantee that this will not affect its structural content,
please go ahead.

It would make it more manageable size-wise, but I wouldn't spend your
time on it (unless you plan to do it programmatically):

  - The file is huge and the duplicates are harmless (besides
    contributing to its size).

  - The file is automatically generated using
    and any manual effort will be wasted after it's regenerated.
