An SC is needed along the lines of:
• Applications shall not disrupt or disable activated features of
other products that are identified as accessibility features, where
those features are developed and documented according to industry
standards.
• Applications also shall not disrupt or disable activated features of
any operating system that are identified as accessibility features
where the application programming interface for those accessibility
features has been documented by the manufacturer of the operating
system and is available to the product developer.
[Ref: S508 1194.21 Para (b) Softtware Apps]

This is relevant because authors misapply techniques or  implement
them incorrectly / incompletely leading to confusion  and
inconsistencies.

Thanks,
