• The removal of the debug-only assertion in the OOM handling path may reduce diagnostic feedback in debug builds; ensure that this change is intended and that alternative diagnostics are in place if needed.

#if defined(_DEBUG)

src/coreclr/vm/codeman.cpp:5146

• [nitpick] Consider renaming 'pwzJitNameMaybe' to a clearer name such as 'tempJitName' or 'jitNameTemp' to enhance code clarity.

LPWSTR pwzJitNameMaybe = NULL;

src/coreclr/vm/appdomain.cpp:922

• The removal of the debug pause loop controlled by 'INTERNAL_PauseOnLoad' should be verified to ensure that it does not impact developers who rely on this mechanism during debugging.

#ifdef _DEBUG

src/coreclr/md/compiler/regmeta.h:2059

• Removal of 'm_bKeepKnownCa' is appropriate for cleaning up unused configurations; please verify that no dependent logic assumes its presence.

bool        m_bKeepKnownCa;             // Should all known CA's be kept?

src/coreclr/md/compiler/regmeta.cpp:66

• The elimination of 'm_bKeepKnownCa' initialization aligns with the header changes; ensure that metadata attribute processing continues to function as expected.

m_bKeepKnownCa(false),

src/coreclr/md/compiler/custattr_emit.cpp:1027

• Updating attribute handling to use only 'props->bKeepCa' should be verified to ensure that removing 'm_bKeepKnownCa' does not alter the intended behavior for known custom attributes.

*bKeep = props->bKeepCa || m_bKeepKnownCa;

src/coreclr/inc/clrconfigvalues.h:111

• The removal of unused config values like 'INTERNAL_EnableFullDebug' should be cross-checked with all modules to ensure no inadvertent dependencies remain.

CONFIG_DWORD_INFO(INTERNAL_EnableFullDebug, W("EnableFullDebug"), 0, "Heavy-weight checking for AD boundary violations (AD leaks)")

src/coreclr/inc/clrconfigvalues.h:392

• Ensure that the coordinated removal of config values such as 'INTERNAL_MD_ForceNoColDesSharing' and 'INTERNAL_MD_KeepKnownCA' does not affect any legacy code paths or fallback behaviors.

RETAIL_CONFIG_DWORD_INFO(INTERNAL_MD_ForceNoColDesSharing, W("MD_ForceNoColDesSharing"), 0, "Don't know - the only usage I could find is #if 0 (?)")
