If the ZX Spectrum support is to be further refined/divided, it would be more logical to divide it into ZX Spectrum and ZX Spectrum 128 libraries. ZX Spectrum +2 is just Amstrad's branding of the ZX Spectrum 128 re-release of the 128 platform (yes it added a cassette player etc. but the platform is exactly the same; all 128 games work on +2 and vice versa). Same for ZX Spectrum +3 (although some +3 items would have the format distinction (3" disk vs cassette) which is already supported by the PriceCharting variant feature (note that ZX Spectrum ROM Cartridge releases are already listed on the site as variants).
TLDR: do nothing or introduce ZX Spectrum 128 platform.
...and if we really want to be pedantic, ZX Spectrum 16K could be a platform on its own since 48 (and 128) KB games don't work on ZX Spectrum 16K which was a legitimate release. But i personally think that's not necessary. Happy to be outvoted if i am wrong.
