SPARC is doing just fine for the context of existing Solaris customers.

ARM, RISC-V and CHERI have similar memory tagging capabilities for Linux/Windows users.

The elephant in the room are Intel/AMD not being able to deliver on that front, after several failed attempts.

In other words, it's a legacy product. There's no future roadmap for SPARC, unlike ARM, x86, POWER, and Z.

From my limited reading on the topic, even Fujitsu has moved on to ARM. Maybe someone can pop in here with a correction to that?
