         PackageLicenseExpression value across all packable projects and errors when they

  <!-- Target frameworks that source-build doesn't support/include.
       Consumed by the package source generator (TFM filtering) and package validation (baseline framework ignore list).
       MSBuild::Escape() prevents wildcard glob expansion when used in ItemGroup Include attributes.
       KeepPlaceholder="true" instructs the package source generator to retain placeholder files (_._)
       for the excluded target framework even though its assets are otherwise filtered out. This prevents
       consumers from incorrectly falling back to another TFM's assembly when the package intentionally
       ships no asset for that TFM (e.g. System.Runtime.CompilerServices.Unsafe, where the implementation
       was moved inbox). It is only applied to the modern .NET TFM families where such fallbacks matter. -->
