Happy Birthday!
I have 6 LCBRs myself, 5 are still in use actually. I have mine paired to both my Hue Bridge and certain bulbs around the house like bathroom, closet lights, hall light. Places where I just want simple control of the lights and still have control of the lights from Hubitat via the Hue Bridge integration.
The LCBR buttons cannot be programmed with the Hue Bridge or HE, but are just not "stolen" away so that both the Hue Bridge and the remotes can control the light(s). Here's where first learned about that trick. I then later bought one of the Trådfri bulb and bridge kits when they first came out just to test what was possible and came to discover that's essentially how their entire system works. Played around with ST and the Trådfri remotes and then wrote how to do essentially the same thing with a ST hub, which at the time gave you more control over the Trådri bulbs than IKEA'a own bridge did. I'm fairly certain you could do similar with HE if you wanted to. They would pair as "Device" here, instead of "Thing".
I started out with the LCBRs on Wink, where you can program the buttons, but they were always terribly slow and unreliable in that configuration. As simple remotes paired directly with the Hue Bridge and Bulbs though, they're rock solid. Still, I wanted the control I had with Wink, just not the problems and that's when I first learned about what was possible with the Smart Bridge Pro, and @stephack 's ABC. So I wrote a post about how to configure that on ST and that led me to discover Hubitat and their far superior built-in integration with the Lutron Smart Bridge Pro, with no dependency on a cloud. Ordered an HE the next day. 
So for me, LCBR are fine for doing those simple tasks and I do the fancy stuff with my Pico remotes. The one next to my bed for example controls the bedroom light ON/OFF and dimming, the lower dim button turns one bulb on to low with a singles press, the middle button locks all the doors, the button button turns off the lights upstairs with a single press and holding the bottom button runs my goodnight sequence.
Enjoy your day and the new toys!
