The thing is that there is (for all intents and purposes) no difference between ECE and plugins.
Actually, ECE is a plugin. The only difference is that it helps web-designers switch plugin providers.
That's it. No more security. No more standardization.
As a user, you still depend on the goodwill of the ECE provider throw you a bone. If you use a slightly niche OS (say, OpenBSD on ARM), you're out of luck.
If Adobe decides that it's not worth their time to develop a plugin for PaleMoon, they won't and you're out of luck (or will MS let their ECE plugin run on Linux, or Google's run on FF?). You (as a user) won't be able to switch to another provider. It all depends on the provider.
