Yeah indeed. Newer nodes have field replaceable diplexers that can switch from a 5-85MHz mid-split to a 5-200MHz high-split return path.

The plan going forward is to push towards Remote PHY, where there's a 10Gb Ethernet link to the node and the only RF segment is from node outwards, rather than sending an analogue carrier down the fibre. This will improve RF performance to the home and substantially reduces space requirements in the hub site.

Will require more power than existing nodes, though may be compensated for by improved power supplies and replacements of active amplifiers with nodes.
