As Lars Marius pointed out, the TM/XTM specs don't require it.
But as I pointed out, one must often take into account application
demands and operate accordingly.
As always, good engineering is taking into accounts project
requirements as much as possible, and working around technical
limitations. Specifications are only specifications.
