@Aklapper Do you reserve this bug for any GCI student or can somebody else (me?) work on it?

@MarcoAurelio: No GCI tag on this, feel free to go ahead. Will we get a new good first task task filed from you in return? :P

Thank you. I'll give this one a try. Similarly, I'll try to add a new good first task task if I spot one in the future.

So I'm wondering whether we should remove:

	/**
	 * Get the normalised IETF language tag.
	 * @param string $code The language code.
	 * @deprecated This provides backward compatibility; replace with
	 *   \LanguageCode::bcp47() once MW 1.30 is no longer supported.
	 */
	public static function bcp47( $code ) {
		if ( !is_callable( [ 'LanguageCode', 'bcp47' ] ) ) {
			return wfBCP47( $code );
		}
		return LanguageCode::bcp47( $code );
	}

altogether or just the if ( ... from that function.

@MarcoAurelio Sir, I think we can't remove it right now. As per the function definition, It should support MW 1.30 and Currently Its master branch support MW 1.30. and also LanguageCode::bcp47() has added in MediaWiki 1.31

@Jayprakash12345 If this can't be done right now, then maybe we shall set this task as 'stalled' until we can do it. What do you think?
