Will Sass compilation be removed for existing themes and sites?

Hey gang, I guess this is one specifically for the Shopify development team specifically.

I ask as my organisation has a time-boxed usage of our Shopify shop (3~ months in the year) and has very limited resource with which to maintain it, one that largely needs very minimal theming changes year-to-year.

In reference to the Sass deprecation mentioned way back in 2020, have their since been any concrete plans as to actively remove Sass compilation for pre-existing sites and themes? I’m getting increasingly concerned that Shopify will randomly pull the plug without notice, leaving us scrabbling to bring over all of our very specific customisations into the new Sass-less world, during a live campaign.

Thanks for any help, much appreciated.
