MHO: I think its better to use it and report any bugs. My experience is with 5.7 and 7.0, that 'updates' should cover security and bugs. In some cases 'targeting' a niche as a spin.
Running a 64-bit 'puter in 32-bit mode looks like the intended 'market'. But 32-bit users can benefit, extending life-expectancy.
I would imagine theres a lot going on in 64-bitland and pi-ville.
