Yes one can construct edge cases where this isn't ideal.
The normal case though is the quoted files are interspersed
in various columns.

Like this?:

'aaa aaa1' bbb2ddd eee2 ggg0 hhh2
aaa0 'ccc ccc1' ddd0fffggg1
aaa2 ccc ddd2fff0 ggg2
'bbb bbb1' ccc0 'eee eee1' fff1 hhh
bbb ccc2eee fff2 hhh0

You have 3 different spacings between columns. Your argument
of using 3-spaces for an extra quote vs. 2 when not needed is
looking pretty unsupportable since it doesn't use 3 when quotes
ARE needed (it uses 4). The above could just as easily have been:
'"'\''"' bbb0 'ddd ddd1' eee0 ggghhh1
'aaa aaa1' bbb2dddeee2 ggg0 hhh2
aaa0 'ccc ccc1' ddd0 fffggg1
aaa2 ccc ddd2 fff0 ggg2
'bbb bbb1' ccc0eee1 fff1 hhh
bbb ccc2eeefff2 hhh0
And this:
'"aaa'\''"' bb cc0dd2ffgg0 hh1
'aaa aa1' bb0cc2 'eee ee1' ff0 gg1 hh2
aa0 bb2 'ddd dd1' ee ff1 gg2
aa2 'ccc cc1' dd ee0ff2 hh
'bbb bb1' cc dd0ee2gghh0

'aaa aa1' b ccdd ee ff0 gg0 hh0

It's more important to have consistent spacing I think on modern terminals.
But you don't as shown above -- you simply waste an extra space using
3 columns of padding rather than 2.
Anyway with layouts
like this you get more wasted space when a few files have
relatively longer names, irrespective of quoting, which is
a much more common issue.
---
Irrelevant. You are using 3 spaces when no quoting is
needed, instead of 2, forcing an extra column into all output
regardless of name length.
The spacing is increased to 3 to allow for an extra space
for left alignment of non quoted items with quoted ones.
---
As shown above it isn't needed. I have 2 between 2 quoted items,
between a combo w/1-quoted and 1 not, and 2 between non-quoted. 2-spaces
between visible characters in all columns.
The alignment is more important for long listing I think,
but thought it a net benefit for other formats also.
---
For a long listing, you don't multiply the spacing
by N columns. You only have 1 column, so ANY filename w/a quote
would require an extra space for the entire (1) column to line up, but
in a long listing things are still odd looking w/the last column sticking out:
ls -l *[ab]*

Very simply, the new format is wasting space with no justifiable
reason.
