Your "it" is ambiguous and does not actually clarify the situation.

A few months ago I wondered why TLS wasn't enabled by default.  In the
ensuing discussion, it came to light that some popular platforms still
don't support TLS.

As you say, I'd guess it's hard to find a *Linux* system w/o TLS
support.  That said, it does seem a bit silly to *remove* such a
feature; maybe it'll be usable on other platforms soon enough.  Why
not report a bug to your other GL vendors, complaining that they don't
include a kernel ABI requirement tag?
