Multiple Function Apps in a single Consumption Plan?

Question

When I create an Azure Function App via the portal, it's not possible to select whether an existing Consumption Plan is used or a new one gets created.

However, it is possible to do so via ARM Templates.

Azure Function Apps: Organizing the Azure Function Apps under same Consumption Plan discusses this, but it does suggest no implications.

What are the practical differences between having 1-on-1 mapping between Consumption Plans and Function Apps vs. many Apps in a single Plan?

Answer 1

In practice, for apps in a consumption plan, there really is no difference whether they're in a plan created for that app only (trying to avoid the word dedicated here to avoid confusion :) ) or sharing with other apps. The behavior will be the same.
