Do HTAs have been forgotten deliberately or accidentally?

[dumblob]

The following assumes HTA means "native" dynamic HTML applications for Internet Explorer.

IMHO deliberately because:

1. it's M$-specific (not multiplatform)
2. it depends on Internet Explorer (i.e. a big problem in Europe because IE must not be the default browser)
3. it was never polished
4. it doesn't support mobile devices well enough (sure, you can write your own widgets etc. in JS but then some of the selling points are gone)
5. it doesn't have good marketing (compared e.g. to M$ Dynamics which would probably compete in similar market sectors)
