People from standards bodies who work for browser vendors are more like mediators.
Their organization has, you know, an org chart.
Each of them works in an organization that makes browsers (chrome, for example), within another organization (google).
Their own oganization is further subdivided into something like pointy bits, roundy bits and squiggly bits departments.
But those departments are themselves further subdivided - it's rare to work on "CSS" - rather you work on a _part_ of CSS.
People who work on standards largely simply mediate between 'everyone else' and some parts of their larger organizations..
In a very practical sense, this matters a lot, because budgets.
Everything requires time, and there's never enough.
Priorities must be decided, and practically speaking, these need to be balanced with organizational goals, internal goals, and available staff
Why does browser X not advance feature Y,
but chooses to instead advance feature Z
often has less to do with what someone really _thinks_ than the fact that they have bandwidth for Z and not Y.
Why does nobody seem to want to work on, or even discuss, thing Q often is reflective of that as well.
It's not necessarily that they have a problem with it - it's frequently that they can't afford to.
While the web doesn't currently N, we have all of these things it _could_ do if it did is the biggest kind of rabbit hole that scares people off
We look to each other for signals, costs are spread out. If another browser or someone has already done research, collected use cases, maybe has written a decent spec or prototype - it reduces my own cost of involvement.
It isn't cheap!
How do you think it got its name?
