Unclear Requirement: 1.4.12 Text Spacing

Hi there,

First of all, love what you do! Just had a quick question.

*Intent*
I would like to have a discussion about requirement 1.4.12 Text Spacing.
I've seen 3 groups people interpret the success of this criteria
differently. I do believe clarification would be helpful.

*Main Questions*
Are these styles defaults for every website or do these styles need to be
supported? Is there a middle ground to this? Do we need to provide the user
with the capability to change these styles or do we rely on them to know
how to implement via plugin, bookmarklet, or manual css etc and simply
support the style changes?"

*Reference Requirement: 1.4.12 Text Spacing*
In content implemented using markup languages that support the following
text style properties, no loss of content or functionality occurs by
setting all of the following and by changing no other style property:
- Line height (line spacing) to at least 1.5 times the font size;
- Spacing following paragraphs to at least 2 times the font size;
- Letter spacing (tracking) to at least 0.12 times the font size;
- Word spacing to at least 0.16 times the font size.
