If the WinForms related properties were prefixed with "WinForms." it would be easier to differentiate them from others
msbuild properties.
Like

  <PropertyGroup>
    <WinForms.ApplicationManifest>app1.manifest</WinForms.ApplicationManifest>
    <WinForms.ApplicationVisualStyles>true</WinForms.ApplicationVisualStyles>
    <WinForms.ApplicationFontName>Control.DefaultFont</WinForms.ApplicationFontName>
    <WinForms.ApplicationFontSize>9</WinForms.ApplicationFontSize>
    <WinForms.ApplicationHighDpiMode>PerMonitorV2</WinForms.ApplicationHighDpiMode>
  </PropertyGroup>

ℹ The common phrase is "makes a conscious decision."

@omariom I've also seen people make their tooling consume XML property content similar to this:

​  <PropertyGroup>
    <WinForms>
      <ApplicationManifest>app1.manifest</ApplicationManifest>
      <ApplicationVisualStyles>true</ApplicationVisualStyles>
      <ApplicationFontName>Control.DefaultFont<ApplicationFontName>
      <ApplicationFontSize>9<ApplicationFontSize>
      <ApplicationHighDpiMode>PerMonitorV2</ApplicationHighDpiMode>
    </WinForms>
  </PropertyGroup>
