Bigger issue
Is that some browsers cant be updated. (the TLS wiki has a compat matrix)
For instance, old Kindle Fires are stuck with Kitkat, and the version of Chrome on it is stalled at a version that supports 1.1 but not 1.2.
Disabling a protocol blocks access to those divices, and that's a hard sell to customers who sell to impoverished nations, etc.
Biting the hand that feeds IT
