I'd care about that.
Buy a bigger monitor :-).
On a more serious note, I think the number of indentation levels should
be fairly low regardless of their width. If someone uses 2-space
indentation so they can fit 20 nested ifs, the other programmers should
complain during code review: Not because the lines are too long but
because the nesting is too deep.

I'm not sure what a "sub-tab stop adjustment" is. I think that for the
"1 tab per indentation level" style, tabs would be used only for
indentation, nothing else, and preferably only for block-level
indentation.
So a python function might look like this with 8 spaces per tab:
def·foo(a_parameter,·another_parameter,
········an_optional_parameter=DEFAULT_VALUE,
········another_optional_parameter=None
····):
→x·=·a_parameter
→a·=·[
→····{·'x':·1,···'y':·2,····'z':·3·},
→····{·'x':·0.4,·'y':·3.14,·'z':·1.618·},
→]
→if·another_optional_parameter:
→ →r·=·(
→
→····(another_optional_parameter·*·a[0]['x']·+·another_parameter·*·b[0]['y'])
→ →····/
→ →····(a[1]['x']·+·a[1]['y']·+·a[1]['z'])
→ →)
→else:
→ →r·=·another_parameter·*·0
→return·r
(I'using → to represent a tab here and · to represent a space.)
And like this with 2 spaces per tab:
def·foo(a_parameter,·another_parameter,
········an_optional_parameter=DEFAULT_VALUE,
········another_optional_parameter=None
····):
→x·=·a_parameter
→a·=·[
→····{·'x':·1,···'y':·2,····'z':·3·},
→····{·'x':·0.4,·'y':·3.14,·'z':·1.618·},
→]
→if·another_optional_parameter:
→ →r·=·(
→ →····(another_optional_parameter·*·a[0]['x']·+·another_parameter·*·b[0]['y'])
→ →····/
→ →····(a[1]['x']·+·a[1]['y']·+·a[1]['z'])
→ →)
→else:
→ →r·=·another_parameter·*·0
→return·r
Note that everything still lines up nicely.
