Is a limit of 50 IP addresses still realistic for home use? UTM vs XG (when will UTM be retired)?

Question

I found a closed, 5 year old discussion with the same subject which bares revisiting. 
 With IPs in just about every technical device (camera's smart TVs, appliances, lighting, speakers... the list goes on and on) is 50 still feasible for Sophos UTM and what exactly happens when you reach the limit. 
 I'm showing: Number of IP addresses currently in use: 68 (exceeds license by 13). I've tested IPs at the top and bottom of the list and from what I can tell they work perfectly and I can ping google.com from them. I do receive some email alerts but other than that I don't see that it's blocking anything. 
 I'm at the latest firmware and pattern version: Firmware version: 9.711-5 Pattern version: 210032 
 Questions: 
 1. Can someone from Sophos please address this issue and ask management/dev if they would remove this limitation as it doesn't appear to be enforced and it can be gotten around by either subnetting or adding another router? It's just a nuisance with no real gain for anyone. 
 2. Some have suggested migrating to XG Firewall but other say that the product lacks maturity and features. What are the differences between the two products? 
 3. I was surprised that when I went to the bookmark I had for UTM ( https://www.sophos.com/en-us/products/free-tools/sophos-utm-home-edition.aspx ) it redirected me and took me to the XG Firewall page. Does this mean that UTM is going to be sunsetted and replaced the XG? If so when? 
 4. I'm running on 2 Intel based SFF PCs in an HA config. If XG Firewall is the replacement for UTM is there a migration path?

Hello Damon Dawson , Thank you for reaching out to the community, well yes that for sure XG being a next gen product will be replaced soon. You can refer the r etirement calendar for Sophos products here: https://support.sophos.com/support/s/article/KB-000035279?language=en_US In terms of difference well UTM 9 is based on open-suse and XG is based on customized Debian OS which offers next gen features like SD-WAN and Ikev2 in IPsec etc. Migration: https://docs.sophos.com/nsg/sophos-migration-assistant/v1/UTM%20Migration%20Portal%20Guide.pdf https://docs.sophos.com/nsg/sophos-migration-assistant/v3/sfos_migration_assistant_sg.pdf Sophos UTM 9 to Sophos Firewall Migration Tool: https://partnernews.sophos.com/en-us/2022/02/products/new-sophos-utm-9-to-sophos-firewall-migration-tool/ UTM 9 is limited to 50 IPs with its free Home license and had no limitations on what hardware it is run on (if you have 64GB RAM you want to throw at it, go for it - but it won't benefit you though) and nothing can be done from the dev/mgmt.
