That’s fairly disappointing. Looks like this deficiency won’t be addressed till WS-15 then.
Someone already did it for me~
Actually, it shouldn't be disappointing. This is COMPLETELY expected given the C2 lasted like what, one or two batches? Before the 15 took over. The C2 *is* a temporary transition after all, and a really short-lived one at that. It's not worth the hassle.
To be fair radar blocker isn't something that could easily added to existing engines. Other older US engines like F110 and F414 also don't have radar blocker even when they expected to power stealth aircraft like Kaan and KF-21. Better to wait for WS-15 and WS-19 rather than making the stop gap engines more complicated.
Do you have a link to the video?
Well, are we sure WS-15 and WS19 do have radar blockers?
Hopefully yes, it's the basics for a 5th generation engine. All US 5th generations have it.
They were intended from their inception to power fifth generation aircraft, it would be very strange from them not to.
I guess the main reason to not include it in WS-10 series is that the loss in thrust/other performance metrics is not worth it.
Officially they will never say anything for years even after service. Luckily we may see it once they are in service. Indirectly we can be pretty sure they do.

One thing to note, the blocker is both for infrared and radar signature reduction as stated in the summary section even though the title says intrared only because infrared research is the purpose of the paper. The summary also refers to F-119's implementation.
