Hello, I propose to separate setting the debugging level of XS loading in XSLoader and the mode of loading XS. More precisely I propose a new environment variable TEXINFO_XS_DEBUG set to 0 in the default case, that could be set to 1 to mean something similar to current TEXINFO_XS=warn and to 2 to mean something similar to current TEXINFO_XS=debug.
This is needed to be able to have debugging while selecting a different loading mode than the default, such as required or requiredifenabled. -- Pat
