We do not update the local layout of our .lyx files because users
would then not be able to export to older formats. For example, if a
2.2.0 user exported a template to 2.1.x format and tried to open the
file in LyX 2.1.x, there would be an error because the file would
contain a local layout whose format is too new. The root reason for
this is that we do not convert layouts to older layout formats.
