Support for thicker arrows

[ralphS16]

When one wants to highlight a specific path in a commutative diagram, it could be interesting to play with the thickness of arrows (instead of using colors). In terms of UI/UX, it seems easy to add to quiver as an additional slider (with position, offset, etc.). However, I am not sure what is the best way to achieve this in tikzcd. Inspired by this TeX.SE post, I wrote the following code that generates the following diagrams with three different levels of thickness. I am sure the output could be improved by tweaking the code (maybe using relative units).

\[
\tikzset{LA1/.style = {line width=1pt, -{Classical TikZ Rightarrow[length=3pt]}}}
\tikzset{LA2/.style = {line width=1.5pt, -{Classical TikZ Rightarrow[length=3pt]}}}
\tikzset{LA3/.style = {line width=2pt, -{Classical TikZ Rightarrow[length=3pt]}}}

\begin{tikzcd}
