Please file bugs against us at https://github.com/google/perfetto/issues! We're always very interested in seeing traces which are hitting performance issues. We take them seriously and are responsive at fixing them (or at least explaining what makes it hard to fix).
As I note in the post, we optimize for the needs of Android/Chrome developers so we may not necessarily know about whatever condition you are hitting with your trace!
However, the restriction only apply to asop/pixel devices.
For other devices, often there is a way to extract unique id/ imei with hidden api without any premissions.
Good to know, this probably explained why the notionally transparent artwork was imported with a white background. But the fact that it’s not a true .ai import I don't think this is ever going to be a concern to me because I never use SVG to typeset flowing blocks of text. The main things I'm concerned about are:
1) Path and style integrity
2) Artboard dimensional integrity
3) Export file quality
In my testing, I was able to open a file I had edited and saved in Illustrator, export it as an SVG, it was an utterly pixel-perfect drop-in replacement for a previously exported SVG. I was also able to confirm that all of the SVG files I care about can be opened directly, edited and exported with no errors. That's enough for me to confidently say goodbye to Illustrator forever. It's robust enough that I know I can deal with the occasional import glitch if it ever does happen.
There are some really annoying things about Designer, though - like how it insists on rasterizing Gaussian blurs, even though SVG supports them as a vector operation...
