formatnum and transforming 0 1 2 etc. digits

Some wikis have a {{formatnum}} template which, in formatting numbers, transforms 0123456789 to ౦ etc. for te.[1]

This rule is not currently in MediaWiki itself, hence numbers produced by MediaWiki e.g. in Special:Statistics or as output of the formatnum magic word are kept as is. Is this still the desire of "te" translators/users?
