The Lancaster Consensus says:

Some distributions offer an "XS" version or a "Pure Perl" version that can be selected during configuration. Currently, each of these has their own way for users to indicate this, which makes it impossible for CPAN clients or other build tools to help users select automatically.

Going forward, the "spec" for Makefile.PL and Build.PL will include command line options to request a "pure Perl only" build. These will be:

So, applying the inverse logic, if the user or their environment has not specifically requested the pure-perl version by this mechanism then you would be abiding by the consensus to attempt the XS install and inform the user of failure to do so when appropriate.

That would probably be my approach but it's hypothetical as I don't maintain any XS modules.
