No. CLIC is not inline with PLIC apart from the name. CLIC is aimed for microcontroller class systems. That's why, it is an option for M platform.
ACLINT provides the local interrupts that high end systems capable of running Rich OS i.e. Linux require.
Timer, IPI (both S-mode & M-mode).

That's why, ACLINT is an option in OS-A platform but not in M platform

Can we close this issue or is there anything else to discuss on this topic?

Ok thanks. What is the difference between ACLINT and CLINT?

It can probably be closed (it might just be confusing for me) ...

The difference between ACLINT and CLINT is described in Section 1 Introduction of the ACLINT spec here https://github.com/riscv/riscv-aclint/blob/main/riscv-aclint.adoc.
I am closing this PR. Please reopen if there are still more questions.
