Inconsistency of bigger braces

[zepinglee]

A minimal piece of XeLaTeX code:

\documentclass{article}
\usepackage{amsmath,unicode-math}
\setmathfont{STIX2Math.otf}
\begin{document}
\[ f(x) = \begin{cases} 0, \\ 1.       \end{cases} \]
\[ f(x) = \begin{cases} 0, \\ 1, \\ 2. \end{cases} \]
\end{document}

Output:

The former brace is so “curly” that it is inconsistent with the latter one. Is this an intensional design?

Probably not intentional. This is closely related to #117. I'll add it to be reviewed as part of the 2.0.1 milestone.

The second, taller brace is composed of stacked elements, so needs to be straight. The first is an individual glyph, so can be more naturally formed, following a traditional curvature for this character. I agree that they look inconsistent when viewed together.

Q. Should the individual brace glyphs (various sizes) be made less curvy so that they coordinate visually with taller braces built from stacked elements? [This would apply only to the Math font; the braces in the Text fonts would remain as is.]
