IMHO, based on ST’s direction of sunsetting (aka killing) the wildly popular “Echo Speaks” as a “platform performance issue”, do we really think that ST/WebCore is going to be long lived once the project management team looks at the next highest performance issue shared app. WebCore made ST’s automation capabilities 100% better than any other 4th generation language product I’ve ever used. It was and is ahead of it’s time. Of course, being a great end user developed shared app will not have any weight in the decision to place it on the upcoming chopping block!
Not to be doom & gloom in this exciting ST migration, I predict a 2021 announcement that ‘ST automations’ will sunset the ‘Classic WebCore’ smartapp in favor of a more streamlined ST offering. For many ST users who do more than a simple ‘if trigger then scene/device’, that will be the real nail in the ST coffin, given that WebCore does 99.9% more than ST automations.
It goes without saying, that WebCore does run on another home automation platform and some users with advanced automation requirements may seek alternatives.
