Come on, inkscape 1.0 is not _that_ buggy. It has been around for a whole year (with a few fixing releases in-between), and it's the version present in Debian 11. If it really has grave bugs (I really mean grave), then those should be filed separately, and I should work on getting them fixed as patches on top of 1.0.2.
Then, concerning the ftbfs of 1.1. I know of it of course. Just that I've been busy over the past month. I'm as weirded out by that test failure as you, especially since I couldn't reproduce it anywhere else.
But no, I'm not going to ignore a test failure just because it's skipped in other architectures for different reasons: I'll need more convincing reasons.
If you'd like other bugs in inkscape 1.1: opposed to 1.0.2 it's doing some kind of unaligned memory access somewhere (yet to debug), which makes it crash on armhf when run on arm64 hardware. I was basically forced to ignore that test failure on Ubuntu and that annoyed me enough, I really don't want to ignore tests just because it's convenient for somebody.
