Maybe, but as an(other) aficionado of Deno for smallish projects where Node is irrelevant, I don't feel like these panders to the mainstream hurt anything.

To the contrary, they make every conversation about using Deno easier, even where we don't and won't use Node (including NPM packages).

I mean sure, they consume some of their resources that might in some ideal (to me) world be spent on something more relevant (to me), but in this world it seems like engineering resources well spent. ¯\_(ಠ_ಠ)_/¯
