doesn't appear indifferent or hostile
TL;DW: there is interest in supporting Typst, but there are roadblocks:
* Higher priority work currently being done on ArXiV (moving from Perl to Python/cloud)
* No "standard" Typst distro
* Support team needs to be re-trained for a new language
* Persistency: TeX has 30+ years of history; will Typst be around in 30 years? Will current code compile? Will existing documents be supported?
haven't watched it but my only data point for that claim is this post: https://www.reddit.com/r/typst/comments/1dcu3p8/i_contacted_...
