[Tagging] support and advertising:support : question on wiki edition

[Paul Desgranges]

Hello

To prepare discussions on 
https://wiki.openstreetmap.org/wiki/Key:support I wish I can firstly 
transform the wikitable found in section 2 of this page into a specific 
template page (for example Template:Map Features:support) so that its 
future translation in other languages is easier. But is there any 
possibility to have template pages for any proposed feature, ('proposed' 
by opposition to 'already adopted' feature) ? In that case that new 
template for support would need to be created for example with this kind 
of name 'Template:Proposed Map Features:support' .... How in that case 
reference this template from the page 
https://wiki.openstreetmap.org/wiki/Key:support

Thank you in advance for your advice

Paul
