Hi Martin,
About this change, now. My current feeling is that it should be an optional behavior. It is very possible to pass options to the PO4A modules, so that users may choose how to handle tbl macros. David, do you think that it would do the trick?
Sure, making this new tbl handling optional (or adding an option allowing to restore the previous behavior), would make this change a lot less disruptive (allowing any project to adopt it or not at their own pace). Not making it the default for now, and announcing that the default will change in the future, would IMHO nicely address the loudly announce [future] disruptive change request.
Regards
David
