Should you be concerned?
That’s the real question. Many consider monthly to be simply too unstable, bug ridden and that is why they have chosen to use semi-annual (or another) update channel. It a choice between getting the latest features & fixes and also bugs vs. what should be more stability but longer delays in receiving new features & fixes.
The choice is yours, but just be aware of this upcoming change so you’re not caught off-guard.
