Beamer: pause by default after frametitle

Question

As the title says. I use \beamerdefaultoverlayspecification{<+->} in my presentation. By default, beamer displays a new frame with the first item or piece of text already visible. However, I want to first display only the frametitle (e.g., the title is a question I want to explain before I go on to provide answers). Right now, I can do this manually like this:

\begin{frame}\frametitle{This title needs some explanation}
  \pause
...

But this has to be done for each frame, and it also has all sorts of unexpected effects (e.g., it seems to mess with the beamerpauses counter, but I don't understand what it does exactly). Is there a way to have a pause after the frametitle by default for all the frames? And if there is, is it also possible to revert back to the default behavior for a single frame (in case I don't want a pause after the title on a specific frame)?

You can patch \beamer@checkframetitle commmand and add \pause command if boolean \ifafterftpause is true, for frames without a pause after frametitle just change to \afterftpausefalse

\documentclass{beamer}
\usepackage{lipsum}

\newif\ifafterftpause
\afterftpausetrue % default

\makeatletter
\def\beamer@checkframetitle{%
\@ifnextchar\bgroup\beamer@inlineframetitle{{}\ifafterftpause\pause\fi}}
\def\beamer@inlineframetitle#1{%
\@ifnextchar\bgroup{\frametitle{#1}\framesubtitle}{\frametitle{#1}\relax}%
\ifafterftpause\pause\fi    
 }
\makeatother     

\begin{document}

\begin{frame}
\frametitle{Title}
    \lipsum[2]

\pause

\begin{itemize}
\item text
\item text
\end{itemize}

\end{frame}

{\afterftpausefalse %  no pause after  frame title    

\begin{frame}{Title}
    \lipsum[1]
\end{frame}
}

\begin{frame}{Title}
    \lipsum[2]

\pause

\begin{itemize}
\item text
\item text
\end{itemize}

\end{frame}

\end{document}

With beamerswitch class

You need to add \mode<all> at the beginning

\PassOptionsToClass{aspectratio=169,10pt}{beamer} 
\documentclass[beamer]{beamerswitch}
\usepackage{lipsum}

\newif\ifafterftpause
\afterftpausetrue % default

\makeatletter
\def\beamer@checkframetitle{%
\@ifnextchar\bgroup\beamer@inlineframetitle{{}\ifafterftpause\pause\fi}}
  \def\beamer@inlineframetitle#1{%
    \@ifnextchar\bgroup{\frametitle{#1}\framesubtitle}{\frametitle{#1}\relax}%
\ifafterftpause\pause\fi    
  }
\makeatother

\title{Title}

\begin{document}

% for beamerswitch class
\mode  
<all>

{\afterftpausefalse\frame{\titlepage}}

\begin{frame}
\frametitle{Title}
    \lipsum[2]

\pause

\begin{itemize}
\item text
\item text
\end{itemize}

\end{frame}

{\afterftpausefalse %  no pause after  frame title    

\begin{frame}{Title}
    \lipsum[1]
\end{frame}
}

\begin{frame}{Title}
    \lipsum[2]

\pause

\begin{itemize}
\item text
\item text
\end{itemize}

\end{frame}

\end{document}
