Is Microsoft planning firmware updates for Surface Laptop 3 devices for 2011 Secure Boot key?

As many people know, the UEFI Secure Boot Key provided as part of the Windows devices firmware is expiring in June of 2026.  Microsoft have announced plans to update these keys for most Surface devices, but have not made any such announcement for Surface Laptop 3 devices.  Will the company issue updated firmware for these devices before June?  Or, does the company recommend that users replace these devices before the 2011 key expiration date?

The information publicly available is sparse, but it does appear that Microsoft no longer intends to update firmware for Surface 3 Laptops - which is fine, except that the after the key expiration, these devices will be substantially unusable, with impacts to UEFI Secure Boot, BitLocker and more...  This is a Windows problem, and I will personally be very disappointed if Microsoft chooses to abandon users of these machines...
