TermMax didn't start with the exact system it runs today. Earlier versions of this style of fixed-rate matching leaned on an order-book approach, where lenders and borrowers effectively waited for a counterparty on the other side of a specific rate and term before a trade could execute. TermMax's current design replaces that with what it calls range orders, sitting on top of an AMM foundation, and I think the reasoning behind that switch says a lot about what actually breaks in a pure order book.
An order book works beautifully when there's constant two-sided flow. Fixed-rate DeFi rarely has that, since any given market splits liquidity across multiple maturities and multiple assets, which thins out the order book for any single combination fast. Waiting for a matching counterparty at your exact desired rate and term isn't a small inconvenience in that environment, it can mean a trade simply doesn't fill.
Range orders solve the thin-liquidity problem by letting market makers and curators set a pricing curve across a range of rates rather than a single fixed quote, and the AMM aggregates every order placed into that market so a taker's trade executes instantly against combined liquidity instead of hunting for one counterparty. Market makers keep pricing autonomy, since they choose the curve, while takers get the instant execution normally associated with pooled AMMs, without the counterparty search that made the earlier order-book model slow to fill during quiet periods.
What gets traded away is some of the precision an order book offers to a market maker who wants to quote an exact rate with no curve at all. I'd call this a reasonable trade for a fixed-rate market this early in its adoption curve, where execution reliability probably matters more to growing the user base than marginal pricing precision does for a small number of sophisticated makers.
