is Xtensa still officially supported? (Noob Question)

[ahsanu123]

i just found rt-thread this week, i start to explore the source and try to learn the example and the docs, in Readme.md image i see Xtensa chip architecture, and fortunately i have several esp32-s3 chip in my hand, but i cant really find example or docs about Xtensa architure, so is Xtensa officially still supported now? or it have been removed?

Thank you.
