There's a basic difference here though. Your traditional "installed
components" are pieces of software and data used *by programs on that
system.*

The components we're talking about here are, as far as the system is
concerned, opaque data to be transmitted over HTTP(S) to a web browser
client which then makes use of that data in some manner.

There are no cross-program compatibility issues stemming from having
multiple different versioned copies of such client-side files on a system -
this is why the web development world has standardised on tooling that
*makes it easy to do so*. Different client-side web applications *should*
be able to use different versions of components.

xstatic shoe-horns that freedom of client-side application component usage
into a one-size-must-fit-all world that fundamentally only exists because
programs on a system can get confused when multiple versions are installed
on that system[1].
