To be extra clear, Netlify no longer uses Deno's managed infrastructure, but still uses the Deno runtime. (Source: I work at Netlify.)

Did they have any heads up about this, and/or do they have any roadmap for what's happening now?

If your question is whether Netlify had a heads up about Cloudflare's Deno acquisition and EOL, no, not as far as I'm aware.
