@ADD-SP commented on GitHub (Jul 22, 2021):

The reason we actively dropped compatibility with ngx_http_rewrite_module is that if we wanted to configure the module in blocks location and if, we would have to wait for nginx to locate the corresponding location based on the URI, but this is done in phase NGX_HTTP_FIND_CONFIG_PHASE. If the module is mounted to NGX_HTTP_REWRITE_PHASE, only partial compatibility will be achieved.

Since it is not fully compatible, and since the previous compatibility scheme did not conform to the module development specification, we decided to discontinue compatibility with ngx_http_rewrite_module and mount the module to NGX_HTTP_ACCESS_PHASE.

This does not actually affect the security checks, since in most cases the response the client receives is generated in the phase NGX_HTTP_CONTENT_PHASE.
