Depends what you mean with dead end.

The hardware was deployed in a few million handsets from Samsung
and Sony.

Some have been picked up as targets for PostmarketOS:
https://wiki.postmarketos.org/wiki/Samsung_Galaxy_S_Advance_(samsung-i9070)
https://wiki.postmarketos.org/wiki/Samsung_Galaxy_SIII_mini_(samsung-i8190)

So it is no more dead end than anything else discontinued, and it
has a living community who want it suppored by the mainline
kernel if possible.
