While I personally believe the fears of GCP being deprecated are overblown, the reason you give isn't actually true. Internally, Google is all for deprecating products with a ton of usage if it's inconvenient to maintain. That's why all internal tools got a new UI in the last year or two, because they deprecated the UI framework while everyone still depended on it.

Most of the deprecated Google products have either alternatives or generate no direct revenues. GWT is just a library in the second category, replaceable with a few hundred SWE years. Unlike that, GCP and YT are making real revenues in the order of billions. This is what "core product" means.
