Obscure OS families

I've been expanding my icon pack for the library, and noticed, that there are some OS families, which are quite obscure, in a sense, that they are not really OS families, but rather OS types or something. I am talking about $osFamilies variable and these specific items in the array:

'Gaming Console' => ['WII', 'PS3'],
'Mobile Gaming Console' => ['PSP', 'NDS', 'XBX'],
'Real-time OS' => ['MTK', 'TDX', 'MRE', 'JME', 'REX'],
'Other Mobile' => ['WOS', 'POS', 'SBA', 'TIZ', 'SMG', 'MAE'],

We are just bunching up OSs that have little to no connection to each other. It may also be problematic to keep these lists up-to-date, too. Do we really need these pseudo-families?
There is also 'Other Smart TV' => ['WHS'],, which probably should be 'Whale OS' => ['WHS'],.

I can do the PR to remove/update them, but I think this is worth proper discussion first.

Start by locating the $osFamilies variable and reviewing the four grouped entries plus the 'Other Smart TV' mapping described in the issue. Check existing tests or detection expectations around these families; done requires an agreed taxonomy and corresponding updates validated by the relevant test suite.
