Is it REALLY a bad idea to install Windows 11 on an 'unsupported' system?

I downloaded the little Windows tool, and it told me my PC is not compatible with Windows 11, but it's basically because of the lack of the TPM 2.0 module.
Specs:
CPU: Intel Core i7 8700k
Mobo: Gigabyte Z370 Aorus Gaming
Ram: 32gb DDR4 3200

I'm thinking about upgrading my whole system (Ryzen 7 9700x CPU, with compatible mobo and RAM), instead of bypassing the W11 TPM 2.0 module requirement, all because I've heard that down the line there may be some "incompatibility" or security issues that Windows may require TPM 2.0 for.
And I've also heard that buying a TPM 2.0 module for my mobo just to make it compatible with W11 is not really the best idea either.
