This case is questionable. The term Tlwg here historically reflects
the foundry, but it doesn't apply any more as more fonts are added
to the suite. No Tlwg prefix is added ever.
However, there are some relations in this set:
- TlwgMono and TlwgTypewriter are of the same exact shapes,
except that TlwgMono is purely monospace, while TlwgTypewriter
is monospace with zero-width combining characters.
They are split by the use cases.
- TlwgTypo and TlwgTypist are similar, except that TlwgTypo (the
purely monospace counterpart) also features kerning & anchoring
for controlling combining character advancement, so that it
behaves as a TlwgTypist equivalence. For this pair, TlwgTypo is
an experimental replacement of TlwgTypist, and the replacement
may take place in the future when it's technically sound enough.
- In fact, TlwgTypo/TlwgTypist was originally a redesign of
TlwgMono/TlwgTypewriter for more elegance. So, the former could
finally replace the latter in the end, depending on users' feedbacks.
So, in a sense, they are related somehow. Meanwhile, they also
compete one another to be the best candidate for users.
Thus, whether they should be treated as a single family is still
questionable to me.

I'll consider this for the rest fonts.
