Stanza Divider Lines

[Gabriel Ellsworth]

In The Hymnal 1982, when there are five or more stanzas in a hymn, the
editors often engrave a horizontal line under the number for a middle
stanza. I’m not sure what exactly to call this line; Google suggests
“wayfinding line,” “visual separator,” “stanza divider line,” or simply
“underscore.”

Here are two examples:

https://hymnary.org/hymn/EH1982/142

https://hymnary.org/hymn/EH1982/407

Below is my MWE reproducing the first example, Hymn 142.

Is my approach using \underline good?

Would others use a different approach, such as \draw-hline or \draw-line?
