Thinking about this topic, I'm wondering about the strategy of CiviCRM in terms of supported CMS?
CiviCRM can now be embedded on 5 CMS (DRUPAL 7, DRUPAL 8, Joomla, WordPress and Backdrop) and this asks a lot of work from the community to maintain functioning versions on all of them, but not only because it also involves specific documentation for each CMS or functional differences between CMS because Webform is not Caldera or Gravity form and I don't know about Joomla. I can think of this heterogeneous environment to be more of a drawback in 5 years.
Even if it's very user-friendly, is this strategy sustainable in the long-term? We already use 2 CMS (DRUPAL 7 and WordPress) and with the end-of-life of Drupal 7 we'll probably switch our Drupal instances - some or all of them - to Backdrop in 2021. Which means a 3rd CMS to learn (same-same but always different) and manage.
Is there a decision taken from the board to stop maintaining in the future Drupal 7 or to make CiviCRM a stand alone web application like vTiger for example, to focus on Drupal 8/9 or to go to another direction?
Who knows about this?
