People might be willing to enable an experimental video driver but not an experimental ATA driver. This global-scope "all or nothing" CONFIG_EXPERIMENTAL is totally pointless and _no_ distro uses it in practice. If it's a pure label via which you want to document things as experimental then i'd agree with adding the "Warning: experimental code" to the help section of all the affected Kconfig entries (that way people would be more likely to actually read that label.) but i think your suggestion of per-subsystem and/or per-driver quality levels is superior to that.
