Is there a term or phrase better than "non-strict"?

Why hasn't anyone mooted "weak inequality"? Or are you shunning "weak inequality" too?

Richard Earl, James Nicholson, The Concise Oxford Dictionary of Mathematics (6 ed. 2021)

Inequalities involving < and > are called ‘strict’, and those involving ≤ and ≥ are termed ‘weak’.

Inequalities

Let us recall two notations. "x < 3" means that x is smaller than 3 ― strictly so, namely equality is not allowed. If we wish to allow also equality, we write "x ≤ 3". The latter is called "weak inequality".
