I don't think we can read that much into it. The tweet says the project is nearly finished, and this doesn't sound like a small effort — so it would have started either before WASM was really a thing or when WASM was still a very risky bet. I mean, I don't imagine they'll be jumping to WASM, but I don't think we can read it as "they're deliberately not endorsing WASM" so much as "WASM is still quite new."
Considering they are uniquely positioned to make it happen given their C# buy-in and probably more than just a bit of existing software to leverage, I'd say this is as strong a signal of non-endorsement as it gets.
