I'm also not entirely sure what you're specifically referring to; I haven't seen any deletions today. There were a bunch of deletions of XF1 and XF2 add-ons over the weekend from a specific author who is no longer part of the community.
But, in general, I would expect to see more XF1 resources deleted as a matter of course over time, assuming the resource authors choose to do so.
They are outdated, no longer maintained, and there's little incentive for add-on developers to do so because the market is comparatively tiny compared to XF2.
