Pipeline errors are not properly handled in Gulp v5 about gulp HOT 1 OPEN

However, it does not remove the error event listener.

Would that mean the problem is with streamx and not gulp? If I understood the flow correctly, streamx wraps original 'object' stream with itself. Looking at this part
https://github.com/mafintosh/streamx/blob/625ce37f624aa51cda95fa1bffdc3fae2ecd03a5/index.js#L267-L277

isStreamx(...) is obviously false for node:stream Transform obj, so the 2nd branch is used. Should it instead use the 1st one? Or, some other event setup entirely

I've also noticed that issue with node:stream. However, gulpfile with through2 does seem to work correctly

through2.obj((chunk, enc, done) => { ... }) // original 'readable-stream' object is returned, things seem to work ok

Replacing the above with streamx also finishes the task and shows the error
(minor issue having tsc warning about a type mismatch)

streamx.Transform({transform(chunk, done) { ... })

from gulp.
