biblatex verbose styles and maxnames

Question

Using biblatex+biber, and any of the "verbose" styles, it seems that maxcitenames has no effect. What I would like to achieve is to have citations using \textcite appear with a small number of maxnames, but have the full author list in the corresponding footnote.

Currently I use the following options:

\usepackage[backend=biber,
maxcitenames=2,
maxbibnames=20,
style=verbose-note
]{biblatex} 

Let's cite \textcite{A} here.

I thought this should generate something like the following:

Let's cite Author et al.^1 here.

^1 Author A, Author B, and Author C "Paper title". In Journal, Year.

But instead I get this, as if I had the same large number for both maxcitenames and maxbibnames. Is there a good workaround?

Let's cite Author A, Author B, and Author C^1 here.

^1 Author A, Author B, and Author C "Paper title". In Journal, Year.

MWE:

\documentclass{article}

\begin{filecontents}{test-example.bib}
@article{a,
  author  = {A, Author and B, Author and C, Author},
  title   = {Paper title},
  journal = {Journal A},
  year    = {1921},
}
\end{filecontents}

\usepackage[backend=biber,
maxcitenames=2,
maxbibnames=20,
style=verbose-note
]{biblatex}

\addbibresource{test-example.bib}

\begin{document}
Let's cite \textcite{a} here.
\end{document}

Answer 1

All citations obey the maxcitenames/mincitenames settings, this even includes \fullcite or the first citation in a footnote in a verbose style, which otherwise mimic the bibliography output.

We can make the full citation in the footnote obey maxbibnames/minbibnames instead by redefining the bibmacro footcite:full.

\documentclass{article}

\usepackage[
  backend=biber,
  style=verbose-note,
  maxcitenames=2,
  maxbibnames=20,
]{biblatex}

\makeatletter
\renewbibmacro*{footcite:full}{%
  \usebibmacro{cite:full:citepages}%
  \printtext[bibhypertarget]{%
    \usedriver
      {\defcounter{minnames}{\blx@minbibnames}%
       \defcounter{maxnames}{\blx@maxbibnames}%
       \DeclareNameAlias{sortname}{default}}
      {\thefield{entrytype}}}%
  \usebibmacro{shorthandintro}}
\makeatother

\addbibresource{biblatex-examples.bib}

\begin{document}
\null\vfill % just for the example

Let's cite \textcite{companion} here.

Let's cite \textcite{sigfridsson} here.

Let's cite \textcite{companion} here.
