Proposal to standardise the nesting level of strings

Created by: Moult

I see that most nodes return this pattern [[n]], where n is an integer, a list of three coordinates for a vertex, or a list of two indices for an edge. I also see a lot of this pattern, which makes sense due to the nested list:

x_out = []
for a, b, c in zip_long_repeat(...):
    ...
    x_out.append()

However, then I see some examples like the File Path node which gives ['foo bar']. Shouldn't this be [['foo bar']]?

Another example is the Note node, which gives [[['foo'], ['bar']]]. Shouldn't this also be [['foo bar']], and then another node should split by whitespace, which can then convert it into [['foo', 'bar']]?
