A Framework expansion card was also announced this week. https://frame.work/nl/en/products/wisdpi-10g-ethernet-expans...
That link notes:
"Card supports 10Gbit/s and 10/100/1000/2500/5000/10000Mbit/s Ethernet"
Nice to see; some NICs are shedding 10/100 support. Apparently, it's not necessary to do this, even in a low cost device.
I also appreciate the 10/100 support. I recently needed it for some old voip equipment, and it was shockingly difficult to find an SFP+ module that worked in my 10G switch and supported 100mbps.
100 mode saved me once when I really really really needed to have a connection in that moment, but the ethernet cable glued to the wall that I was using had only three out of eight wires even functioning.
Don’t we need at least four for 100 Mbps?

Low cost? The link mentions no price, only a "notify me" button as far as I can see. Does it show a(n estimated) price point for you somewhere?
$99 when I look at the entry in https://frame.work/marketplace/expansion-cards
Low cost, as in not data center/server grade hardware.
Low-cost devices are exactly where 10/100 is still widely used. On PCs, it's a common power-saving mode.
TVs too.

For those of us who don’t know, how does it save power vs a 1gbe running at low throughput?

100 is needed for embedded stuff, it'd render a lot of devices unusable (wiznet chips are popular and are 100 only). That'd suck.
IKEA smart home hub is also 100mbit.
There are plenty of embedded chips which only provide RMII. No RGMII or alternatives.
Lots of industrial sensors and devices only do 4 wire 100BASE-TX so if there's no fallback to that it would be a paperweight in those situations.

That hasn't been true on switched networks in probably 20 years or so.
Isn’t that only relevant for network topologies that rely heavily on broadcasting to multiple nodes. Eg token ring, WiFi and powerline adapters?
For regular Ethernet, the switch will have a table of which IPs are on which NIC and thus can dynamically send packets at the right transmission protocols supported by those NICs without degrading the service of other NICs.

We have switches now, hubs just don't exist anymore. Switches are not affected by some devices having a lower speed.
Is that really true? If so, is there a saner way to handle this than upgrade all the things to 10GBE? Like a POE ethernet condom that interfaces with both network and devices at native max speeds without the core network having to degrade?

That is complete nonsense and not how switched networks work.
A Framework SFP+ or SFP28 expansion would be sweet.
