I must confess that I have no idea why half-elf and halfling druids weren't allowed in OSRIC, since they are explicitly allowed in the AD&D PH (the former as PCs, the latter as NPCs). My guess is that it was done deliberately as some sort of "legal monkeywrench" so that the designers can point out that OSRIC's various class/race combos are not in fact a direct reproduction of AD&D's, and if that's the reasoning then I can understand and appreciate it, but I still don't like it. It's for reasons like this that I'd never consider OSRIC as a viable substitute for AD&D as my rule-system of choice. However, if I were writing an OSRIC-compatible module (something I have no plans to do at present, but who knows what the future may hold) I could, presumably, resolve this issue by "accidentally on purpose" misinterpreting the OSRIC rules and allowing half-elf and/or halfling druids -- yeah, I made a mistake, one that would be disavowed by the authors of OSRIC, but that's the price of an open license -- people will make mistakes.
(As for the separate issue of halflings in OSRIC being underpowered compared to other races, that was always the case in OD&D and AD&D1, except as thieves. If you chose to play a halfling fighter you were doing it because that's the role you wanted to play (probably you'd just re-read LotR and wanted to be Merry
) and you should have no illusions that you're not playing a severely limited character.)
