Then we need to make that commitment. Windows XP is no longer a minor 
inconvenience such that we can just hack around its missing APIs via 
dynamic linking. It is different enough from modern Windows that XP has 
now become an impediment to shipping new features such as a11y on e10s 
and the newest sandboxing mitigations. Continuing support for XP on 
non-ESR is an option that completely opposes the objective of building 
core strength.
