Correct me if I'm wrong: but if the search buttons are given translatable text descriptions in the .ui file (as is done with most of Sigil's other buttons), won't that text be shown when a theme is applied that doesn't have the search button icons included? That's what happens to the main toolbar buttons if the icon is missing from the theme. A custom theme with those icons missing might be an easy "fix" for those who believe they can't live without the text (provided there's fallback text included in the .ui).

But in general, it doesn't make a lot of sense to me that people wouldn't be able to get used to the new icons eventually. It's not like there's one single other button in Sigil's Main Window that uses text. *shrug*
