:g format drops non significant zeros, and also uses scientific
notation as appropriate; PostScript explicitly supports scientific
notation (PostScript Language Reference section 3.2).

The point is mostly to improve the legibility of the PostScript output.

Do we know if anyone is doing text-file diffs on ps files as part of a test suite? This will break those

I don't know for PS, but I changed all the glyph embeddings for SVG in #17669, and although this seems to have broken some non-compliant SVG renderers (#20910), no one complained about text diffs specifically.
