tikz and pgf libraries are not in the file list used by \listfiles and similar reports in LaTeX. #1424
Description
Brief outline of the bug
pgf uses in its input commands \input without braces and so the primitive \input is used. This means that LaTeX can not store the file name for a report with list files and also not for the new report showing the tagging support status of packages.
Could tikz/pgf please change in pgfutil-common.tex
\def\pgfutil@InputIfFileExists#1#2#3{\pgfutil@IfFileExists{#1}{\input #1\relax#2}{#3}}%
into
\def\pgfutil@InputIfFileExists#1#2#3{\pgfutil@IfFileExists{#1}{\input{#1}\relax#2}{#3}}%
or at least load user facing libraries with \input{..} instead of \input ...?
This should be safe in other formats as all engines now support the \input syntax with braces.
Minimal working example (MWE)
uncomment the one line to see the difference in the log
\listfiles
\documentclass{report}
\usepackage{tikz}
\makeatletter
%\def\pgfutil@InputIfFileExists#1#2#3{\pgfutil@IfFileExists{#1}{\input{#1}\relax#2}{#3}}
\makeatother
\usetikzlibrary{calc}
