Are Shift or AltGr fallbacks sufficient?

5.3.6. Guidelines for selecting key values

If more than one key is being pressed and the key combination includes one or more modifier keys that result in the key no longer producing a printable character (e.g., Control + a), then the key value should be the printable key value that would have been produced if the key had been typed with the default keyboard layout with no modifier keys except for Shift and AltGr applied.

In some Hebrew keyboards the caps lock key also produces significant character assignments, like shift in most keyboards. Perhaps it is necessary to take that into account here ?
