rowcolor and @{} issue

Question

In the next example we can see that
rowcolor does not take into account the declaration @{} in tabular preambles.

Is this a normal behavior?
Is there some elegant way to avoid that spurious filled space?
documentclass{article}
usepackage{xcolor, colortbl}

begin{document}

begin{tabular}{|c|c|c@{}|} 
rowcolor{gray!30}
text & text & text
end{tabular}

end{document}

The package nicematrix with its environment {NiceTabular} tries to solve the problems of the package colortbl.
Here is the output of {NiceTabular}.
documentclass{article}
usepackage{xcolor}
usepackage{nicematrix}

begin{document}
begin{NiceTabular}{|c|c|c@{}|}[colortbl-like]
hline
rowcolor{gray!30}
text & text & text
hline
end{NiceTabular}
end{document}

You need several compilations.
