Running without a thermostat ok?

I didn't want to read 4 pages of conflict so In my experience I have replaced many engines because of overheating. because someone removed the thermostat and at about 2000rpms the lower radiator hose sucks shut cutting of all water flow, most replacement hoses forget the wire insert .. just by 2 cents, hope it helps.

Please enlighten me on why the lower hose needs the spring? is it a mopar thing? is it needed when there is no t-stat? I find the spring hoses unpleasing to the eye, buttt... if there is a need in certain situations id like to know....thanks.
